The Harris matrix is a tool used to depict the temporal succession of archaeological contexts and thus the sequence of depositions and surfaces on a 'dry land' archaeological site, otherwise called a 'stratigraphic sequence'. The matrix reflects the relative position and stratigraphic contacts of observable stratigraphic units, or contexts; Tips. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The Harris Matrix - formulated by Dr. Harris in 1973- is the established way of representing the archaeological stratigraphy of an excavation. The Harris Matrix is a sequential diagram defining relations between stratigraphic units. It is an important method to document the stratification that is destroyed.
Stratigraphic excavation in its basic form involves a process of cleaning the surface of the site; isolating contexts and edges which are definable in their entirety or part and then attepting to excavate or remove contexts in reverse stratigraphic order ( ie, in a backward chronology) – removing and recording he last material activity that occurred on the site back to the first. After removing a context or if practical a set of contexts such as a feature like a pit or wall., the “isolate and dig” procedure is repeated until no man made remains are left on site and the site is reduced to natural.

OVERALL PRINCIPLE: Understand the concept of physical and chronological stratigraphy as well as the methods of recording the sequences.
Stratigraphic excavation
PRINCIPLE: Be able to remove layers and fills in the correct order for structured excavation
![]()
Determining relationships
PRINCIPLE: Be able to analyse and resolve relationships between features, where this is unclear, utilising the most appropriate method for a solution. To understand the relevance of determining relationships within an excavation.
Professional tips:
Understanding stratigraphy is no harder than understanding the way a trifle is created, and should almost always be dug one layer at a time. Try not to excavate any lower layer until you have fully removed the previous one.
The secret to understanding the nature of physical/stratigraphic relationships is the simple question: Are there other actions that happen between the contexts. If yes, then he relationship is physical only.
The best place to record every physical stratigraphic relationship is in the field – you do not get a second chance.
Although some people do not agree with the Harris Matrix – this is the best way to understand the complex relationships between contexts. In many cases, you will not be able to tell which came first, all you have to do is split the matrix lines.

The Harris Matrix was invented in 1973 by Dr. Edward C. Harris and for the first time provided archaeologists with a means to view stratigraphic sequences in diagram form. It has since been adopted by professionals worldwide.

Description. The Corner Detection block finds corners in an image by using the Harris corner detection (by Harris and Stephens), minimum eigenvalue (by Shi and Tomasi), or local intensity comparison (based on the the Accelerated Segment Test, (FAST) method by Rosten and Drummond) method. The block finds the corners in the image based on the pixels that have the largest corner metric values The Harris Matrix system has been accepted as the industry standard in many countries around the world, and Principles of Archaeological Stratigraphy has been translated into ten other languages to date. Its methods are of universal application, for the two components of stratification are always the same: surfaces and deposits. Wolvesey Palace, Winchester, England, 1970-71: The Great Hall in.

The Harris matrix is a tool used to depict the temporal succession of archaeological contexts and thus the sequence of depositions and surfaces on a 'dry land' archaeological site, otherwise. Check images on this post for example of matching. These points are called salient points. Moreover, the corner points tend not to change their 'cornerness' properties when the image is scaled, translated, rotated, skewed, etc. (affine transforms) This is why they are called stable. Some points in the image allows you to uniquely identify. The Harris Matrix - formulated by Dr. Edward C. Harris in 1973 - is the established way of representing the archaeological stratigraphy of an excavation. The Harris Matrix is a sequential diagram defining stratigraphic relations between stratigraphic units. It is an important method to document the stratification that is destroyed by the excavation process and hence a vital tool for. The Harris Matrix (or Harris-Winchester matrix) is a tool developed between 1969-1973 by Bermudian archaeologist Edward Cecil Harris to assist in the examination and interpretation of the stratigraphy of archaeological sites. The Harris matrix is specifically for the identification of both natural and cultural events which make up a site's history
